The designation "transsexual" refers to those who persistently believe their gender to be incongruous with their anatomical morphology. This study involves a group of 21 female sexual reversal surgery (SRS) candidates and a group of 59 male SRS candidates to observe if transsexual cognitive ability patterns are correlated with levels of stereotypic interest patterns. It was found that the gender stereotypic interest patterns reported by male and female transsexuals were not directly related to cognitive abilities in congruence with psychological gender identity. The MMPI MF scale five, utilized to measure culturally prescribed gender role, was compared to the IQ differential derived from verbal and performance differences scores from an abbreviated WAIS (Wechsler Adult Intelligence Scale). Multiple regression revealed a direct relationship only between educational level and IQ difference scores, but there were indications of an indirect relationship between gender interests and stereotypic cognitive abilities. Female transsexuals had significantly higher performance and full scale IQ scores than male transsexuals in opposition to previously reported cognitive pattern differences between the sexes, and may be a result of gender identity and/or sexual issues.
